THOMAS W. MILLER, F ASHLAND, OHIO, ASSIGNOR TO THE FAULTLESS RUBBER ICOMPANY, OF ASHLAND, OHIO, A CORPORATION OF OHIO.

PROCESS OF MANUFACTURING SEAMLESS RUBBER GLOVES.

To all'wkom it may concern.

Be it known that I, THOMAS W. MILLER, a citizen of the United States,residing at Ashland, in the county of Ashland and State of Ohio, haveinvented certain new and useful Improvements Processes of ManufacturingSeamless Rubber Gloves, of which the following is a specification.

My invention relates to seamless rubber gloves, and has for its objectto provide certain improvements in the method of manufacturing the same,as will be hereinafter more definitely pointed out and claimed.

More specifically, my invention relates to the-production of a glove ofthis character having its inner surface, in whole or in part, providedwith a lining of textile material, such as stockinette, and inwhich thecuring process firmly unites said textile material to the rubber body.

In the accompanying drawing :-Figure 1 is an elevation of an ordinaryform used in the manufacture of seamless rubber gloves, a glove beingshown formed thereon,

and the two being partlybroken away. Fig. 2 is an enlarged fragmentarysectional view of the said form and glove, the latter being shownpartially vulcanizedon the outer surface. Fig. 3 is a view similar toFig. 1, showing the glove applied reversed on' a form. Fig. 4 is a viewsimilar to Fig. 2 of the form and glove shown in Fig. 3. Fig. 5 is aview similar to Fig. 3 with textile material applied to the surface ofthe glove. Fig. 6 is a view similar to Fig. 4: of the form and gloveshown in Fig. 5. Fig. 7 is a view partly in section of the completedglove.

In the said drawing, the reference numeral 1 denotes the ordinary formused in the manufacture of seamless rubber gloves, said gloves beingformed in the usual manner by dipping the form into a rubber solution toapply a plurality of coatings of rubber thereto. Said rubber glove soformed by the dippingprocess is indicated by the reference numeral 2,and the same has the usual finishing edge 3 formed thereon, either byrollin the rubber back upon itself, or by applying thereto a strip ofrubber to form a bead, or in any other suitable mannenas' may bedesired. The complete rubber glove so formed is then cured by the wellknown acid or vapor cure, which I will term a cold cure, and whichresults in the glove being vulcanized on its outer surface, as in-Specification of Letters Patent. 7

dicated at 4 in Fig. 2, and practically unvulcanized on its innersurface, as indicated at 5 in said figure, the sulfur of the solutionnot completely penetratiing the rubber. The glove so partiallyvulcanized is then stripped from the form 1 and applied to said form orto a similar form 6 turned inside out, bringing the substantiallyunvulcanized surface 5 of the glove upon the exterior, as shown in Figs.3 and 4:. To this substantially uncured surface of glove the textilematerial 7 is applied, the rubber being more or less sticky causing thesame to adhere thereto, and the glove with the textile material soapplied may then bevul-' canized on that surface by the acid or vaporcure, which will effect a homogeneous union between the rubber andtextile material. Or the textile material may be applied thereto with. aself-curing cement, which will unite the same to the rubber glove, andwill obviate the necessity for the second cure. The completed glove isthen stripped from the form 6 and reversed and will present theappearance disclosed in Fig. 7.

The glove may be provided with a lining of fabric 7 throughout itsentire area, though it will be understood that portions only of theglove may be so lined, for instance, the wrist portion may be lined, andthe fingers and thumb at the crotch provided with lining pieces, and thetips of the fingers may also be so lined. In fact I do not wish to'limitmyself in any particular as to the area of the surface to be lined, assaid lining may extend over the entiresurface or any part thereof.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is y 1. The method of making seamless rubbergloves, which consists in forming the same upon a form by dipping, thenvulcanizing the same in such manner that the inner surface thereof iscured less than the outer surface, then reversing the same upon a form,then securing theretoa layer of fabric, and finally again reversing saidglove to bring the fabric inside.

2. The method of making seamless rubber gloves, which consists informing the same upon a form by dipping, then vulcanizing the same insuch manner that the inner surface thereof is cured less than the outersurface, then reversing the same upon a form,

then applying thereto a layer of fabric, then vulcamzing said fabric tosaid glove, and finally again reversing said glove to bring the fabricinside.

3. Themethod of making seamless rubber gloves, which consists in formingthe same upon a forni by dipping, then cold curing the same from theexterior surface inward,

then reversing the-same upon the form, then applying thereto a layer offabric, then curing said plied, and finally again reversing said gloveto bring the fabric inside.

In testimony whereof I have hereunto affixed my hand, thisv 8th day ofJune, 1915.
